A Miami-Dade woman who had planned a special visit to her husband’s gravesite on Valentine’s Day says she made a truly disturbing discovery: her husband’s gravestone was missing and she wondered if his body was still there.

Jessica Williams is the caretaker to one of the oldest African American cemeteries in South Florida, where community pioneers have been laid to rest. But recently, criminal acts have been disturbing the bodies resting at one cemetery that houses 538 burial plots at in Miami.

A mystery solved is now a memorial dedicated in Lemon City Tuesday morning. Three years ago construction workers building affordable housing unearthed bones on the site. It was later determined those were the bones of Bahamian settlers, some who helped found Miami.
